Anesthetic implications

Preoperative optimization

  • Increased risk of perioperative cardiovascular decompensation

Intraoperative management

  • Hemodynamic goals are to maintain forward flow and decrease regurgitant volume
    • Preload: normal-high to augment CO
    • Afterload: low-normal to promote forward flow
    • Rate: high-normal
    • Rhythm: sinus (rate more important)
    • Contractility: high-normal

Postoperative management

Related surgical procedures

Pathophysiology

  • Hemodynamic sequelae of AI:
    • LA distension > Volume overload > Subendothelial ischemia
    • CHF > pulmonary edema
    • RV failure > pulmonary HTN
  • In acute AI, sudden increase in LV volume can induce cardiogenic shock and pulmonary edema
